eTo all Awilma it may concern V Be it known that we, lViLLIAM L. GilmsoN and Enw'ann F. Roninrrs, citizens of the 'This invention relates to an implementI which is adapted to be utilized for removing and replacing` packing rings. n

In the construction of packlng ringjolnts,

. more especially in the piston rings for the l j pistons o1 engines, the support 'for the packzgrooves for the reception of the rings.

ing ring-or the piston` is .provided 'with The rings are elastic and are constructed and jn'oportioned so as to spring outi'v-.n'dly against the cylinder walls. The grooves are however ot' such a depth that the ring, which is split, must be sprung outwardly in order to be placed in positiom It is very diliicult to remove such a rinbr and to replace it. es-

pecially since the ends are cut diagonal ly or on a bevel, thereby rel'idering their engagement by a tool exceedingly diilicult.

One of they ohjects'o'f this invention is to construct an implement by means of which a packing ring can be sprung` apart, and thus easily removed or replaced.

Another object is to construct the jaws of such an implement so that they will support the ring as well-as spread it, whereby the b the tool entirely.

Further objects will appear from the detail description, taken in connection with the accompanying drawings, .in which- F igure 1 i an elevation, of one form of implement s earn in engagement with a packing ring the ringr being' in collapsed position; Fig. 2 is a similar View showing a 'rind may be handled with and supported by slightly modified formof implement, the im-` and is split so as to form diagonal or beveled ends B.

The implement comprises a pairof pirotally connected members lprovidcd with a prirof jaws 11, pivotally connected to the members 10 by means of pivot pins 12.` The jaws 11 are preferably formed of sheet metal ent,`to 'lorm side walls 13 and an end wall 14. The jaws are slotted as shown at 15,V and thewalls 1,4 above these slots are stamped inwardly'so as to form .V-shaped portlons 16. Ims 17 connect the side Valls 1S and fonm stops which' engage the piston rinlgY as shown in Fig. 2, and the jaws are I curved as shown at 18, so as to conform to the eontoin of the ring. A `pair of links 19 are pivotally connected to the jaws at 20 and to tl members 1() at 21. The lower ends of thelio'iks are provided wtlrslots 22 for the pivot pin or bolt 9.3 which pivotally connects the members l0.

In the construction shownl in Fig. 1. the r struction of the jaws permits them to receive' the .ends of the rings. and the V construction 'US conforms to the beveled ends of the ring so that the implement will not only firmly engage the 4ends of the ring but will also support the same.

The operation in applyinglr and removing `a ring will be obvious from the drawing.

The jaws of the implement arearraneed to engage the .ring as shown, and the ring can then be expanded so that it can be easily slipped over the piston and allowed to contract in its groove. Similarly the rimeT can be expanded so as tovremove the same. The curved construction of the jaws permits them to clear the support for the ring when the ring is to be placed in position, and the provision of the spring 25 permits the tool to behandled withuone hand. The jaws willengage the ring so as not only to expand it but the frictional cngagementis suffiarms 24 and provided with suitable adjusting mechanism engaging cooperating adjusting mechanism on the opposite arm. The link 26 is preferably formed of a single piece of sheet metal bent double and forming a yoke 27 The material is stamped out ,sso as to form recessed portions or bearings e0 28 and 29 forthe receptionv of a threaded link 30 pivotally V-vconnected to the other 'f arm 24. An adjusting nut 31 is mounted on "tbc threaded link 30 in the yoke 27. By-

, ""mcans of this construction, the jaws of the. 2 5 implement can' be spreadapart and locked in :adjusted position. Itwill thus. be seen ythat'fa simple and cheap'adjusting means is provided for adjusting and ocking the 'aws 30 paekinfgfring 'can be easily accomplished.

obvious that various changes ma be @inadefinthe details ofconstruction wit out -fiieparting .frjorn, this invention, and it is, therefore, to'gbeunderstood that this invenfstructionf shown and. described.
